Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International
Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies
casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 3630-2 was prepared by Technical Committee ISO/TC 106, Dentistry, Subcommittee SC 4, Dental
instruments.
This third edition cancels and replaces the second edition (ISO 3630-2:2000), which has been
technically revised.
The following changes were made:
a) tolerances for diameter measurements were aligned;
b) test procedures were aligned with ISO 3630-1.
ISO 3630 consists of the following parts, under the general title Dentistry — Endodontic instruments:
— Part 1: General requirements and test methods
— Part 2: Enlargers
— Part 3: Condensers, pluggers and spreaders
— Part 4: Auxiliary instruments
— Part 5: Shaping and cleaning instruments

Introduction
Specific qualitative and quantitative requirements for freedom from biological hazard are not included
in this International Standard but it is recommended that, in assessing possible biological or toxicological
hazards, reference be made to ISO 10993-1 and ISO 7405.
Attention is drawn to ISO 6360 (all parts) which specifies a 15-digit number for the identification of
dental rotary instruments of all types.
